AI总结:

本文从自旋粒子S矩阵提取双自旋黑洞至自旋四阶的2PM保守势,利用指数化引力Compton振幅,并通过匹配低阶结果及eikonal相位与MPD方程计算验证哈密顿量有效性。

摘要:

从自旋粒子的S矩阵中,我们提取了双自旋黑洞的2 PM保守势,在自旋算符上达到四阶。一个重要成分是所有引力子螺旋度扇区在经典自旋极限下的指数化引力Compton振幅。所得哈密顿量的有效性通过匹配已知的低自旋阶结果,以及从eikonal相位直接计算2PM冲量和自旋踢击,和基于Mathisson-Papapetrou-Dixon方程的测试黑洞散射结果得到验证。

英文摘要:

From the S-matrix of spinning particles, we extract the 2 PM conservative potential for binary spinning black holes up to quartic order in spin operators. An important ingredient is the exponentiated gravitational Compton amplitude in the classical spin-limit for all graviton helicity sectors. The validity of the resulting Hamiltonian is verified by matching to known lower spin order results, as well as direct computation of the 2PM impulse and spin kicks from the eikonal phase and that from the test black hole scattering based on Mathisson-Papapetrou-Dixon equations.
